2. The navigation system according to claim 1 , wherein the shopping cart further comprises a camera module which is disposed on the shopping cart body, coupled to the communication module, and configured to acquire a user image and transmit the user image to the communication module, wherein the communication module is further configured to upload the user image to the server.

3. The navigation system according to claim 1 , wherein the positioning module comprises a Bluetooth module which is disposed on the shopping cart body and coupled to the communication module, wherein the Bluetooth module is configured for communicating with the other Bluetooth modules in a shopping mall where the shopping cart is located so as to acquire communication data, and the communication module is further configured to forward the communication data to the server, and the server is configured to determine a position of the shopping cart in accordance with the communication data.

4. The navigation system according to claim 1 , wherein the shopping cart further comprises a display module which is disposed on the shopping cart body and coupled to the communication module, wherein the display module is configured to display the navigation route received from the communication module.

5. The navigation system according to claim 1 , further comprising a plurality of Bluetooth modules located in a shopping mall.

6. A navigation method for navigating a shopping cart, using the navigation system according to claim 1 , comprising: after a user has selected the shopping cart, associating the user with the shopping cart; acquiring a position of the shopping cart and a parking spot where a vehicle of the user is located; and generating a navigation route in accordance with the position of the shopping mark and the parking spot where the vehicle of the user is located.

7. The navigation method according to claim 6 , wherein prior to associating the user with the shopping cart, the navigation method further comprises: determining the parking spot where the vehicle of the user is located; identifying identification information about the user; and associating the user with the parking spot where the vehicle of the user is located.
